Could it be a Virus/Malware?

Self-explanatory Title. My anti-virus, and my Malwaresbyte has come up with nothing, and it seems legitement. For almost 2 weeks now, my computer (Windows XP prof) has been acting up.

At night, mainly around past 7pm EST (9pm EST has also been a 'favoured' time of this) my computer's screen starts to have colours mixed up. I attempted to take a Screen-Picture and save it so I could upload it here for an example, but I cannot access anything without a pop-up saying something along these lines:

'Insufficient process...'

Insufficient SOMETHING, I am not sure. I think it was memory? Everything, tabs, windows, etc. The Blue parts of my windows

Anywho, that is my problem. It is irritating because it freezes up most of the time, and my attempts at 'shutting off my computer correctly' are in vain as I cannot click anything, and I cannot exit anything at all. Therefore, I manuelly re-boot my PC by tapping this small round button under my Power button on my Hard drive. Nothing saves. Which is why it worries me, since I had to re-do an entire essay.

I have work right now too, and its due soon, so it would be appreciated if someone would figure out what exactly is going on.

I do not believe it is a virus, but I put it here incase, for the experts to look at.

If it is in the wrong section, I would appreciate it if you could move this to the correct place and call for the expertise at such section.

**Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**

Please, never rename Combofix unless instructed.

Close any open browsers.

Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".

Click onthis linkto see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.

NOTE1. If Combofix asks you to install Recovery Console, please allow it.NOTE 2. If Combofix asks you to update the program, always do so.

Close any open browsers.

WARNING: Combofix will disconnect your machine from the Internet as soon as it starts

Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.

If there is no internet connection after running Combofix, then restart your computer to restore back your connection.

Double click on combofix.exe & follow the prompts.

When finished, it will produce a report for you.

Please post the "C:\ComboFix.txt"

**Note 1: Do not mouseclick combofix's window while it's running. That may cause it to stall**Note 2 for AVG users: ComboFix will not run until AVG is uninstalled as a protective measure against the anti-virus. This is because AVG "falsely" detects ComboFix (or its embedded files) as a threat and may remove them resulting in the tool not working correctly which in turn can cause "unpredictable results". Since AVG cannot be effectively disabled before running ComboFix, the author recommends you to uninstall AVG first.
Use AVG Remover to uninstall it: http://www.avg.com/us-en/download-tools
We can reinstall it when we're done with CF.**Note 3: If you receive an error "Illegal operation attempted on a registery key that has been marked for deletion", restart computer to fix the issue.

Make sure, you re-enable your security programs, when you're done with Combofix.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

NOTE.
If, for some reason, Combofix refuses to run, try one of the following:

1. Run Combofix from Safe Mode.

2. Delete Combofix file, download fresh one, but rename combofix.exe to your_name.exeBEFORE saving it to your desktop.Do NOT run it yet.

Please download and run the below tool named Rkill(courtesy of BleepingComputer.com) which may help allow other programs to run.

There are 4 different versions. If one of them won't run then download and try to run the other one.

Vista and Win7 users need to right click Rkill and choose Run as Administrator

You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

OK, I hope it is. It happened to me last night again. My computer went all weird, and I could not click anything. Colours became inverted, like I described at the beginning. I will take a picture with my cell phone next time it happens and post it on here (on this same topic) to show you what I mean.

Maybe it is an internal problem of my hard drive or something...

Appreciated if you kept this topic open and I will post a picture of it and the time of which it happened!
